Monster Hunter Wilds Communication Error S9052-TAD-W79J

Monster Hunter Wilds (MHW), available on Windows, PlayStation 5, and Xbox Series X/S, has experienced various reported errors since its February 28, 2025 release. The S9052-TAD-W79J communication error is a common one, often accompanied by messages like “A communication error has occurred.” This error typically disrupts multiplayer sessions, preventing connection to servers or joining friends' games.

The root cause can be network problems, server overload, geographical restrictions, or compatibility issues. Let's explore some solutions:

Solution 1: Optimize Your Network Connection

A weak or unstable network connection often hinders MHW's ability to maintain a stable server connection, leading to the S9052-TAD-W79J error. Try these steps:

• Wired Connection: Prioritize a wired Ethernet connection over Wi-Fi for improved stability and reduced lag.
• Restart Router: A simple router restart can resolve temporary network glitches.
• Close Background Apps: Free up bandwidth by closing unnecessary background applications, downloads, streams, or updates.
• PC Optimization: Use system optimization software to boost your internet speed and terminate resource-intensive background processes.

Solution 2: Disable IPv6

Disabling IPv6 has helped many players resolve the S9052-TAD-W79J error.

1. Open Control Panel (view by Category).
2. Navigate to Network and Internet > Network and Sharing Center > Change adapter settings.
3. Right-click your network connection and select Properties.
4. In the Networking tab, uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK.

Solution 3: Use Google Public DNS

Switching to Google Public DNS is another effective method.

1. Open the Properties window of your internet connection (as in Solution 2).
2. Select Internet Protocol Version 4 (TCP/IPv4) > Properties.
3. Choose Use the following DNS server addresses, entering 8.8.8.8 (Preferred) and 8.8.4.4 (Alternate).

Solution 4: Adjust Windows Defender Firewall

Some users found success by temporarily disabling or configuring their firewall. Caution: Disabling your firewall increases vulnerability to malware. It's safer to allow MHW through the firewall instead.

• Option A (Temporary Disable - Use with Caution): Open Windows Security, navigate to Firewall & network protection, and disable the firewall for each network type (Domain, Private, Public). This is a temporary measure only.

• Option B (Allow MHW through Firewall):

  1. In Windows Security, go to Firewall & network protection > Allow an app through firewall.
  2. Click Change settings > Allow another app > Browse, locate the MHW executable, and add it.
  3. Check the boxes for Private and Public, then click OK.
